METHOD OF GENERATION AND CONCLUSION OF THE ELECTRON BEAM IN THE FIELD OF HIGH GAS PRESSURE, TO THE ATMOSPHERIC

摘要

FIELD: electronics.;SUBSTANCE: invention relates to the field of creation of focused electron beams and their output to the region of increased pressure, to atmospheric. Plasma cathode is created by a low-voltage reflective discharge with a hollow cathode, the electric field is accelerated by electrons that escape from the plasma cathode. Accelerated electrons are conducted through the radiation path to the focusing magnetic field and the focused electron beam is emitted into the atmosphere through two diaphragms, the area between which is pumped out. Additional pumping of the light pipe is carried out, reducing the pressure between the diaphragms by forming an air jet, transverse to the direction of the main airflow from the area of the beam use.;EFFECT: technical result is about using of an electron beam in the working region in the pressure range from a deep vacuum to an elevated one, including atmospheric pressure.;1 cl, 2 dwg
